Description

Technical Field

[0001] This utility model belongs to the technical field of aquatic equipment, and in particular relates to an aquatic net cage that is easy to clean. Background Technology

[0002] Aquaculture cages, as important facilities in modern fisheries, are widely used in nearshore and freshwater aquaculture. Traditional cages typically consist of a fixed frame and non-removable netting. While simple in structure, they have significant drawbacks: after long-term use, algae, shellfish, and organic pollutants (such as fish feces and other fish metabolites) easily adhere to the netting surface, causing mesh blockage, hindering water exchange, and consequently affecting water quality and fish health. To maintain cage cleanliness, farmers need to frequently manually wash or replace the netting, a time-consuming and labor-intensive process. Furthermore, manual washing can easily damage the netting, increasing maintenance costs. Summary of the Invention

[0003] To address the problem of netting being easily clogged and difficult to clean, this utility model provides an aquatic net cage that is easy to clean. The technical solution is as follows: it includes a net cage frame, which adopts a polygonal prism skeleton structure design, wherein the bottom surface of the polygonal prism has at least four sides. Fixed nets are fixedly installed on the upper and lower bottom surfaces and two opposite surfaces of the net cage frame. Sliding grooves are opened in the upper and lower parts of the net cage frame, and movable net frames are slidably installed in the sliding grooves. A net cage connecting flange is fixedly installed on one of the fixed nets, and the net cage connecting flange is connected to the drive mechanism.

[0004] In a preferred embodiment, the movable frame includes a movable frame and a movable net. The movable net is fixedly installed inside the movable frame. Several fixing holes are opened on both sides of the movable frame, and pull rings are fixedly installed at both ends of the movable frame.

[0005] In a preferred embodiment, the cage frame has cage fixing holes at both ends, and the cage frame and the movable cage frame are detachably connected by fixing bolts passing through the fixing holes and the cage fixing holes; when the fixing bolts are tightened, the movable cage frame is fixed in the sliding groove, and when the fixing bolts are removed, the movable cage frame can move freely in the sliding groove.

[0006] In a preferred embodiment, several buoyancy devices are fixedly provided on both sides of the cage frame. Each buoyancy device includes two connecting plates, an upper and a lower connecting plate, a connecting shaft is fixedly provided between the connecting plates, and a float is slidably provided on the connecting shaft.

[0007] In a preferred embodiment, the cage frame is provided with lifting lugs.

[0008] In a preferred embodiment, the drive mechanism includes a reducer and a drive motor, with the output end of the drive motor connected to the input end of the reducer, and the output end of the reducer connected to the mesh box flange via a transmission shaft.

[0009] In a preferred embodiment, a transmission connection flange is fixedly provided at one end of the drive shaft near the mesh box connection flange, and the transmission connection flange is detachably connected to the mesh box connection flange by bolts.

[0010] As a preferred option, both the cage frame and the movable frame are hollow structures. The hollow structure increases the buoyancy of the cage frame and the movable frame in the water, thereby reducing the risk of the cage sinking to the bottom.

[0011] The beneficial effects of this utility model are:

[0012] (1) Rotation cleaning: The connection flange of the net cage is rotated by the drive mechanism (drive motor, reducer, transmission shaft), which can change the direction of the underwater part and the above-water part of the net cage frame. This design solves the problem that traditional net cages cannot be thoroughly cleaned because the underwater part is difficult to contact. Operators can directly clean the entire surface of the net cage without diving, which significantly improves cleaning efficiency and reduces labor costs and time investment.

[0013] (2) Quick fixing and disassembly: The movable net frame can be quickly fixed or unlocked by using fixing bolts through the matching of fixing holes and net box fixing holes; when it is necessary to replace or clean part of the net, simply remove the fixing bolts and move the movable net frame along the slide to achieve quick replacement or cleaning of part or the whole net surface;

[0014] (3) Reduce biological attachment and disease risk: Regularly turning over the net cage and cleaning the surface can effectively remove attached algae, shellfish and fouling organisms, reduce the growth of pathogens, ensure the cleanliness of the aquaculture water, reduce the probability of aquatic animals getting sick, and improve the survival rate.

[0019] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0020] Example

[0021] like Figure 1-3 The aquatic cage shown is easy to clean and includes a cage frame 1. The cage frame 1 adopts an octagonal prism skeleton structure design. Fixed nets 2 are fixed on the upper and lower bottom surfaces and two opposite surfaces of the cage frame 1. Sliding grooves 3 are opened in the upper and lower parts of the cage frame 1. Movable net frames 4 are slidably arranged in the sliding grooves 3. A cage connecting flange 11 is fixedly installed on one of the fixed nets 2. The cage connecting flange 11 is connected to the drive mechanism.

[0022] Furthermore, the movable frame 4 includes a movable frame 401 and a movable net 402. The movable net 402 is fixedly installed inside the movable frame 401. Several fixing holes 403 are opened on both sides of the movable frame 401. Pull rings 404 are fixedly installed at both ends of the movable frame 401.

[0023] Furthermore, the two ends of the cage frame 1 are provided with cage fixing holes 7. The cage frame 1 and the movable cage frame 4 are detachably connected by fixing bolts 5 passing through fixing holes 403 and cage fixing holes 7. When the fixing bolts 5 are tightened, the movable cage frame 4 is fixed in the sliding groove 3. When the fixing bolts 5 are removed, the movable cage frame 4 can move freely in the sliding groove 3.

[0024] Furthermore, several buoyancy devices are fixedly provided on both sides of the cage frame 1. The buoyancy device includes two connecting plates 8, and a connecting shaft 9 is fixedly provided between the connecting plates 8. A float 10 is slidably provided on the connecting shaft 9.

[0025] Furthermore, the cage frame 1 is provided with lifting lugs 6.

[0026] Furthermore, the drive mechanism includes a reducer 12 and a drive motor 13. The output end of the drive motor 13 is connected to the input end of the reducer 12, and the output end of the reducer 12 is connected to the mesh box connecting flange 11 via a transmission shaft 14.

[0027] Furthermore, a transmission connection flange 15 is fixedly provided at one end of the transmission shaft 14 near the mesh box connection flange 11, and the transmission connection flange 15 is detachably connected to the mesh box connection flange 11 by bolts.

[0028] Furthermore, both the cage frame 1 and the movable frame 401 are hollow structures. The hollow structure increases the buoyancy of the cage frame 1 and the movable frame 401 in the water to reduce the risk of the cage sinking to the bottom.

[0029] The above-mentioned aquatic net cage is used as follows: the entire net cage is lowered into the water using the lifting lugs 6, the movable net frame 4 of the upper part of the net cage is pulled out, and fish and related aquaculture items (such as aquatic plants) are put in. When the net cage needs to be cleaned, the movable net frame 4 above the water is inserted into the slide 3, and then the fixing bolts 5 are tightened to fix it in the slide 3. The drive motor 13, reducer 12, drive shaft 14 and drive connection flange 15 are connected in sequence. The drive connection flange 15 is connected to the net cage connection flange 11 by bolts. The drive motor 13 is started to drive the entire net cage to rotate. The movable net frame 4 of the upper part is moved to the water, and the movable net frame 4 of the water is moved to the water. At this time, the staff only need to stand on the shore or on the boat to wash the part of the net cage that was originally not able to be washed underwater. After washing, it is decided whether to disassemble the movable net frame 4 above the water as needed.
